Zur Untersuchung des reziproken Gitters von Einkristallen mit Hilfe von Kikuchi-Diagrammen

A new method has been developed for the examination of the reciprocal lattice of single crystals by means of Kikuchi patterns. The Kikuchi bands belonging to a zone axis may be used to locate the lattice points lying within the reciprocal lattice plane, which is orthogonal to this axis and passes through the origin. For the investigation of the whole reciprocal lattice, a series of reflection patterns is taken at different orientations of the specimen. Each group of Kikuchi bands belonging to a zone axis is used to locate the reciprocal lattice points in a section orthogonal to the respective zone axis. The angles between the section planes are obtained by recording the angle of rotation between successive exposures and by considering the inclinations of the zone axes relative to the primary beam. In a perspective drawing the reciprocal lattice region near the origin is then composed of these sections.
